WATER-PAN FOR HOT-AIR IEUENACES.

necaosa.

Application filed March 5,

To all whom it may] concern:

Be it known that l, ERNEST ELMER ENoLn- MAN, a citizen of the United States, residmg at Roanoke, in the county of Roanoke and State of Virginia, have invented certain new and useful Improvements in ater-Pans for Hot-Air Furnaces, of which the following is a specification.

The present invention relates to means for humidifying air passed through an air heating furnace.

The object is to provide a simple and effective structure which can be readily placed in position in a furnace without materially altering the structure, and will not only supply vapor to the air passed through the furnace, but will also act as a collectmg agent for dust and the like carried by the air or falling through the floor grating or other openings.

A further object is to provide means whereby the water can be readily drawn oif and as readily supplied.

An embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a view partly in elevation and partly in section of a well known type of furnace, showing the novel means in place therein Fig. 2 is a horizontal sectional view,

Fig. 3 is a detail sectional view on an enlarged scale,

Fig. 4. is a horizontal sectional view of a slightly modified form of construction.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment disclosed, a so-called pipeless furnace is employed containing a central combustion chamber 5 of any desired character surrounded by a casing 6 forming an air circulating chamber. This air circulating chamber is subdivided by a cylindrical depending partition 7 into an outer annular air intake flue 8 and an inner outlet line 9 that immediately surrounds the combustion chamber 5. A grating 10, as is well known, covers both the upper intake end of the flue 8 and the discharge end of the flue 9. The partition 7 terminates short of the bottom of the furnace, affording communication between the lower ends of the flues 8 and 9.

In the space below HM partition 1' and ex- Specification of Letters Patent. Patented D 21 1920 1920. Serial No. 363,388.

tending centrally from the wall of the combustion chamber 5 to the outer casing wall 6 is a circular water pan in the form of a V-shaped trough 11 having a central supporting flan e 12 and having an inclined bottom, as Wlll be clear by reference to Fig. 3, the flange 12 tapering from one end to the other. A supply pipe 13 is connected to the higher end of the trough and extends outside the casing wall 6, being provided with an upturned terminal 14,- and in this upturned end can be placed a funnel 15 or other suitable fluid-directing means. From the lower end of the trough extends a dis charge pipe 16, which may be closed by any suitable means, as for example, a plug 17 It will be obvious by reference to Fig. 1 that 1f water is placed in the pan or trough, the air passing through the furnace will pass over the surface of the water and therefore not only absorb water therefrom, but will give up a relatively great amount of dust and dirt carried by said air. This will gravitate into the pan and can be drawn off with the water by opening the discharge pipe 16. A fresh supply can be introduced easily through the pipe 13.

As a modification of the structure above described, the means illustrated in Fig. 4 may be employed, the only difference being that the trough is divided into sections 11*, each of which is provided with a supply plpe 13 and a discharge pipe 16.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. An air heating furnace comprising a combustion chamber, an air circulating chamber surrounding the same, and a water pan in the lower portion of the air circulat- 7 ing chamber and comprising an elongated troughhaving a bottom that inclines downwardly, means extending to the outside of the chamber for supplying liquid to the higher portion of the pan, and means connected to the lower portion of the pan for drawing oil the contents thereof to permit the flushing of said trough.

2. An air heating furnace comprising a combustion chamber, an air circulatlng chamber surrounding the same, a substantially V-shaped water trough in the lower portion of the air circulating chamber having a tapered supporting flange that provides a downwardly inclined bottom to the trough, means for supplying water to the higher end of the trough, and means for drawing off the water from the lower end of the trough to permit the flushing of said trough.

In testimony whereof, I a'liix my signature in. the presence of two witnesses.
